CODE-SENDING APPARATUS.

Application filed January 14, 1928.

This invention relates to app: 1atus for sending or transmitting' codesignals7 the same having particular reference to devices of this naturein which a keyboard similar to a typewriter is employed` having aseparate key for each code character so that a single depression of akey will send or transmit the corresponding code signal or signals.

One of the principal objects of the present invention is to provide asimple and, improved apparatus for transmitting code signals over arelay circuit which includes a common wiper contact element adapted tobe moved in a defined path and ay characterforming contact element foreach code character initially movable to an active position in the pathof movement of the wiper contact together with electrical means formoving the Wiper contact and electrical means for holding thecharacter-forming Contact element in its active position, saidelectrical means being included in a circuit having a. switch operableby the movement of thc character-forming contact element to its activeposition for closing the circuit and a second switch operable to openthe circuit upon completion of the movement of the wiper contact overthe character-forming contact for instantl)7 breaking the circuit andallowing the parts to be returned to a normal position.

T he invention further comprehends means for regulating or controllingthe speed of movement of the wiper contact element during thetransmission of the signals so as to conform to the speed at which thcsame may be received, while allowing for a quick or instantaneous returnmovement of the wiper contact to a normal position.

Other objects reside in the comparative simplicity of construction ofthe apparatus. the economy with which the same may be produced and thegeneral efficiency derived therefrom.

lith the above received and other objects in view, reference is had tothe following description and accompanying drawings in which there isexhibited one exam le or embodiment of the invention.r while t eappended claims define the actual scope of the invention.

In the drawings` Figure l is a diagrammatic view illustratin theapparatus;

of a key illustrating particularly the character-forming contactelement.

Referring to the drawings by characters of reference. 10 designates arelay circuit in which included a common wiper contact element 11.suitably mounted for movement in a defined path, the same beingillustrated as carried by rotary member 12 suitably mounted on a shaft13. The member 12 is adapted for rotatory movement in one directionelectrically by any suitable means, but, as illustrated, this meansconsists of a solenoid 14 having a core 15 which is movable in onedirection when the .solenoid is energized. The core 15 has attachedthereto a cable 16 which is trained about a sheavc 17 attached to therotary member 12.y the opposite end of the cable beingr connected to acoiled contractile spring 18. lt thus follows that when the solenoid isenergized the core will be moved upwardly to stretch the spring 18, andat the same time to turn the sheave 17 and the rotary member 12 in thedirection indicated by the arrow. This causes the common wiper Contactelcinent 11 to be moved therewith in its defined path of movement. lVhcnthe solenoid is (le-energized it is obvious that the spring will exert apull to move the core in an opposite direction and consequently rotatethe member 12 and the wiper contact 11 in the opposite direction to anormal inactive position. The solenoid is arranged in a circuit 19 whichalso includes a normally open switch 20 having spring-pressed contactclements 21 and 22 which are normally separated by springs 23 and 24.The contact element 22 is provided with an actuator head 25.

The circuit further includes in series with the solenoid anelectromagnet 26 and a .seeond switch 27 having a stationary contactelement 28 and a movable contact element 2), the latter being carried bythe rotary member 12. Keys 3() fulcrumed at 3l are included in the relaycircuit 10 and each key is provided with a code character-formingclement or terminal 32 which are normally disposed out of the path ofmovement of the wiper contact element. but which are adapted to beselectively moved into the path of movement thereof by depression of akey-actuator lever 33 operatively connected to the key in any suitablemanner such as by a link 34. Each key is provided with aninsulatcdarmature piece which is designed to be attracted by theelectromaenet Itlach key further provided `l:ith an insulated bloei-f:which designed to contact vith the actuator head oi' the contact clrmentof the switch 20.

In use, when the operator depresses the lceyactuator lever 33, the key30 connected therewith is swung" upwardly in the direction of the arrowinto the. delined path ot' movement ot the wiper contact 11 which is common to all ot the keys employed. The initial movement of the key 30causes the block 3G to engage the actuator head 25 to torce the contactof the switch 2O into engraeement with the Contact 21. Thissimultaneously closes the circuit 19 to the electromagnet 26 and to thesolenoid 14, causing the electromagnet to attract and hold the key inits raised active position while the solenoid core moves upwardlyagainst the action of the spring 18 and turns or moves the common wipercontact ov r the face of the character-forming contact element In orderto regulate and prevent a too rapid movement of the core 15 of thesolenoid, and a corresponding excessive speed ot' movement ot' the wiper11, the solenoid core is suitably connected with a piston or plunger 3Twhich is mounted in a closed cylinder 38 having open ports 39 at one endand having an adjustable outlet or pressure escape valve 4() adjacentthe other end. In this way, adjustment of the escape valve 4t) regulatesthe speed of movement of the solenoid core when the same is energized soas to control the speed of movement ot the wiper contact 11, while whencle-energized the solenoid core and wiper contact may return to a normalposition instantly under the action of the spring 18. Att-er the wipercontact is passed over the acc ot the character-forming contact element2Q, the switcn element 29 of the switch 2T moving with the rotary member12 will di=eugage the Contact element 28 et the switch land break thecircuit 19, causing` the magnet 26 and solenoid 111 to be fle-energized.Instantly the springs 23 and 24 oiz the switch :20 function to swing thekey 30 downwardly to its normal position out of the path ot returnmovement of the wiper contact 11, at the same time breaking the circuit19 at the switch 20. Immediately following the breaking' of the circuit19fat the switch 20, the contact element 29 of the switch 27 will againengage the contact element 2S thereof and re-establish the circuit atthis point until the next succeeding operation.
